uv pip compile --universal resolves to wrong python_full_version specifier on python3.8 #6412
Description
Happens with uv version 0.3.1 on a Ubuntu 20.04.6 LTS x86_64 machine.
Steps to reproduce.
- Create a python3.8 virtualenv
python3.8 -m venv venv- Create
requirements.in
coverage[toml]
pandas
matplotlib
- Run uv pip compile in the virtualenv:
uv pip compile --universal -o requirements.txt requirements.in- This generates:
# This file was autogenerated by uv via the following command:
# uv pip compile --universal -o requirements-py38.txt requirements.in
contourpy==1.1.1

# via coverage
tzdata==2024.1
# via pandas
zipp==3.20.0 ; python_full_version < '3.10'
# via importlib-resources
For which the third to last entry (tomli) is wrong:
tomli==2.0.1 ; python_full_version == '3.11'
# via coverage
converage needs tomli for python < 3.11.
Running the same uv binary in a python3.9 virtualenv however, generates the correct python specifier:
# This file was autogenerated by uv via the following command:
# uv pip compile --universal -o requirements-py39.txt requirements.in
contourpy==1.2.1
# via matplotlib
coverage==7.6.1
# via -r requirements.in

# via importlib-resources
Also, running it without the --universal flag generates a correct requirements.txt:
# This file was autogenerated by uv via the following command:
# uv pip compile -o requirements.txt requirements.in
contourpy==1.1.1
# via matplotlib
coverage==7.6.1
